Have the old episodes been remastered or something? I'm watching one of the old mid-90s on Sky One HD and it looks like a Flash animation, can't decide whether I like it or not.

Edit: Apparently they have, they've cut the top and bottom of the image rather than stretching (apart from TV screen scenes). Channel 4 still seem to either stretch them on the standard channel and show in their original aspect ratio on the HD channel, no remasters on either.
